Are R4DS obsolete now?

Strange R4DS error. Anyone else got it?

• The MicroSD card in my R4DS encountered a strange error. I was loading music, games, etc on to the card via the USB reader that came in the box, and... "13.2mb remaining space". I beg your pardon? The only thing that's on there is 100mb of games and 200mb of firmware, at worst. On a 1 gig card! I backed up the firmware temporarily, put the external SD reader into Disk Utility under OS X and wiped it. Fine now. Has anyone else had this? Phantom data that the R4DS can't pick up, but tells you is there? I often delete ROMs from the Games folder, and nothing happens - size remaining stays the same as if nothing had happened to the ROM.

• Answer:

  either there is a virus slowly taking space in ur drive (this happens to me too) or there is something wrong when ur drive was formatted so thats why it still think some space u've deleted is still there or the drive has its own recycling bin so the stuff stays there anyway even though u delete it
